17.5 Hyper-Threading Technology

Intels

®

Hyper-Threading technology boosts system performance without higher clock rates or adding more

processors which is also an optimization of the power consumption. Hyper-Threading works by duplicating
instructions streams, called threads. This allows a CPU to pretend to be two logical processors on the
operating system which must support this technology. Individually the logical processors can be halted or
interrupted or can execute a thread independently of the other logical unit.

Important: Hyper-Threading is only supported on the 1.6 GHz version (Article no.: 03001-0000-16-0 and 03001-0000-16-2)

17.6 Fan Interface

If a fan is added use this interface to connect a fan to cool off the CPU. The connector only supports 5V
fans. A three pin fan includes a pulse output (sense) which allows the control of fan speed.

17.6.1 Connector

The fan interface is available through connector J3203.

To protect the external power lines of peripheral devices make sure that

- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
